By virtue of the structure described, a ventilator has been providedthat will permit considerable circulation of air through the windowopening without those portions of-the window frame important to theproper functioning of the lower window sash, such as the guideways andthe sill portion upon which the sash is adapted to rest, being subjectedto deterioration by contact with rain or snow, as Suchwindow frames areusually constructed of wood. Further, by reason of the manner in whichthe air deflecting head is mounted for movement between limits, whereinit is constrained formovement to definite positions with respect to thewindow opening, its adjustment is easily accomplished, and by virtue ofthe manner in which the head is removably mounted on the window frame,its attachment thereto may be effected with little effort.

Another important advantage of the invention is that, when the airdeflecting head is in position within the window opening with the frontedges of its end-walls in sealed connection with the parting-strips ofthe window frame, rain or snow is prevented from coming in contact withthe links, springs, holding apparatus and other mechanism disposed atthe side of each end-wall. Thus corrosion of said mechanism is greatlyprevented, and the proper operation of the Ventilator assured.
